Abstract

The study of the production of electroweak boson-pairs provides an important test of the electroweak sector of the Standard Model. New Physics effects, direct or indirect, can modify the strength of the gauge-bosons self interactions, inducing changes in the diboson production at the LHC energies, even if the scale of New Physics might lie beyond the LHC reach. A promising channel for the diboson studies is the production of WZ boson-pairs with the fully leptonic decay mode, which introduces a compromise between statistical and systematic limitations of the measurement. In this talk the progress of the 13 TeV WZmeasurements will be discussed, as well as the interpretation of the measurement for setting limits on physics beyond the Standard Model, and the first studies on the W and Z boson polarisation in WZ processes.
